A Chronic Disease Medication Data Sharing Model Based on Blockchain

Chronic Disease Medication Data (CDMD) includes a great number of valuable patients’ information collected from smart pillboxes. CDMD sharing in the Chronic Disease Medication Compliance Management System is helpful to improve the medical level and service. Blockchain provides a new way to solve the problems, e.g., privacy security, user control rights, and single point of failure, in data sharing. In this paper, we propose a secure CDMD sharing method in a decentralized way based on blockchain and cryptography technology to realize secure data sharing among entities by a model of ’on-chain deposition to confirm rights, off-chain storage of transmission data’. This method can enable secure sharing of medication administration data between institutions, avoiding the trustless problem caused by data centralization.
